Title:
CONTINUOUS POLYMERIZATION PROCESS FOR USE WITH PA6-66 COPOLYMER AND PA6-66 COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2018/090624
Kind Code:
A1
Abstract:
A continuous polymerization process for use with a PA6-66 copolymer and a PA6-66 copolymer, wherein the PA6-66 copolymer is prepared by using three-stage continuous polymerization. Using an addition method which combines a solid nylon 66 salt and an aqueous solution of the nylon 66 salt such that caprolactam and the 66 salt are uniformly mixed before a reaction, and a highly random copolymer is obtained by means of polymerization. In the PA6-66 copolymer, content of PA66 salt percentage by mass may be up to 60%, while a melting point of the copolymer is between 162.6°C-210.6°C, and relative viscosity is between 2.4-3.6.
